ings, forming part of this specification, in

which Figure 1 is a top plan view of my improved tender end sill. Fig. 2is a front elevational view, partly in section, of my improved tenderend sill. Fig. 3 is an end elevational viewof the same.

This invent-ion relates to a new and useful improvement in end sillsdesigned particularly for tender underframes, and while shown as aseparate casting in the drawings, it could be an integral part of theunderframe.

The particular feature of my present i11- vention is the provision ofstep extensions at each end of the end sill, said extensions beingpreferably integral with the end sill,

provided with means for retaining wooden treads, which latter are boltedor otherwise secured in posit-ion. These wooden treads, of course, couldbe replaced by integral metal treads, if desired.

In the drawings, 1 indicates the end sill which may be of any approvedconstruction with respect to its interior bracing members, butpreferably this end sill has front and rear vertical walls 2 and 3,which at the end sills are extended downwardas at 4 to form supports forthe stops.

The end wall of the end sill is cut away as at 5 to provide a flatopening, and on the bottom wall 6 are preferably arranged flanges 6constituting retaining walls for the tread portion '7. Other flanges 6are arranged at diiferent points to support similar treads 7. r

I claim:

1. An end sill, having its end wall removed so that the bottom wallthereof will constitute a tread, said end sill having integral downwardextensions at each end, said extensions being also provided with treads.

,2. Thecombination with an end sill having open ends so that the endportions of its bottom wall constitute treads and removable tread platespositioned on the end portions of said bottom wall.

3. An end sill having its end wall removed so that the bottom wallthereof constitutes a step, tread plates applied to the end portions ofthe botom wall, depending walls at the ends of said end sill,transversely disposed plates between said depending walls, and removabletread plates positioned on said transversely disposed plates.

4. A cast metal end sill having its ends open so that the end portionsof the bot-tom wall of said sill form,steps, and tread plates applied tothe end portions of said bottom wall.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses, this 13th day of November,1911.
